Lengthen Inner Type Short Names

[SentryMan]

Change JsonB Generation to use expanded short names for inner types. Fixes cases where inner types have conflicting short names.
Now can have a controller like this.

  @Post("/outer1/state")
  List<Outer1.State> testInnerClass(Outer1.State state) {

    return List.of(state);
  }

  @Get("/outer2/state")
  Outer2.State testInnerClass2() {

    return new Outer2.State();
  }

The generated route will now have the JSON type adapters look like this:

  private final JsonType<Outer1.State> outer1$StateJsonType;
  private final JsonType<Outer2.State> outer2$StateJsonType;
